Kubota B6100DT Parts Catalog – 135-Page OEM Breakdown for Tractor Repairs

You know the drill: you’ve got a Kubota B6100DT on the lift, the owner says “it’s making a noise,” and you need to find the right bearing or seal before you even touch a wrench. The generic parts listings online? They’ll get you a box with the wrong internals. That’s why I keep a copy of the factory Parts Catalog within arm’s reach. This is the exact 135-page document Kubota issued for the B6100DT. It’s not a rehash, not a compilation – it’s the original OEM book, scanned and searchable.

Engine Group: Crankcase, Cylinder Head, and Valve Train

The catalog breaks the engine down into groups that match how you’d actually disassemble it. The CRANKCASE GROUP starts on page 1 of the document, listing every bolt, gasket, and plug with its factory part number. The CYLINDER HEAD GROUP covers valve guides, seats, and the head gasket. You’ll find the VALVE ROCKER ARM GROUP with the exact rocker shafts and adjusters – no more guessing which side the lock nut goes on. The CAMSHAFT GROUP and PISTON CRANKSHAFT GROUP show the timing gears, thrust washers, and bearing inserts. If you’re rebuilding the top end, you need these exploded views to order the right parts the first time.

Transmission and Axle: 1st through 5th Shaft Groups

Transmission work on a B6100DT is pure misery without the factory diagram. This catalog dedicates separate groups to the 1ST SHAFT 4TH SHAFT GROUP, 2ND SHAFT REVERSE SHAFT GROUP, and 3RD 5TH PTO SHAFT GROUP. You can see exactly which bearings, spacers, and snap rings live on each shaft. The DIFFERENTIAL GROUP and FRONT AXLE CASE GROUP cover the ring gear, pinion, and axle shafts. The TRANSMISSION CASE GROUP shows the housing and all the little plugs that leak. I’ve watched guys split the case twice because they ordered one wrong seal – this catalog eliminates that.

Fuel System: Injector Nozzle and Injection Pump Breakdown

The NOZZLE HOLDER GROUP and INJECTION PUMP GROUP appear twice in the book (once for engine, once for the fuel system section), which tells you Kubota considered them critical. Each page shows the internal parts – delivery valves, plungers, nozzle tips – with the OEM part numbers. Same for the FUEL FILTER GROUP and FUEL TANK GROUP. If you’re chasing a low-power complaint, you can cross-reference the injector parts without pulling the pump off the tractor.

Hydraulics, Steering, and Brakes: Control Valve and Oil Pressure Groups

The CONTROL VALVE GROUP and two OIL PRESSURE GROUPS (1 and 2) give you the spools, springs, and seals for the three-point hitch. The STEERING GROUP shows the steering column and tie rod ends. Brake work is covered in the BRAKE GROUP and BRAKE ROD GROUP – you’ll see the shoes, return springs, and actuator levers. No aftermarket catalog lists these with the same clarity; you’ll often find the wrong “supersession” part if you trust third-party sites. Stick to this OEM source.

Why the Factory Parts Catalog Beats Aftermarket Copies

Every aftermarket parts database I’ve used for the B6100DT has errors – missing digits, incorrect quantities, or parts that didn’t fit the American-spec models. This catalog is the original Kubota document, printed for the factory, with part numbers that match the actual tractor. The ALL PRODUCT INDEX on page 2 lets you jump to any group by reference number (e.g., 01T001 for CRANKCASE GROUP). When you’re ordering seals for the CYLINDER head or valves for the VALVE rocker assembly, having this in front of you saves a 45-minute phone call to the dealer.

Does this parts catalog include torque specifications or repair procedures?

No. This is strictly a parts listing catalog – exploded diagrams, part numbers, and quantities. For torque values and disassembly steps, you need the separate service manual. But for ordering cylinder head bolts, camshaft bearings, or transmission gears, this is the only source you should trust.

Can I use this catalog to identify parts for the B6100D (non-turbo) version?

Yes. The catalog covers the B6100DT and includes a separate section titled FRONT WHEEL GROUP B6100D[AMERICA] on page 11042 of the index. Most engine and transmission groups are shared. Cross-check the part number against your serial number, but the diagrams are identical for both models.

You’ve got a tractor that needs parts. Don’t waste a week waiting for the wrong shipment. The factory Kubota B6100DT Parts Catalog gives you the exact OEM numbers for every crankshaft bearing, every camshaft gear, every transmission shaft. Order it, print the pages you need, and tape them to the toolbox. Kubota V3300-T-E2B-EPS-1 Parts Catalog – 53-Page OEM Parts Breakdown covers a different engine family if you work on industrial models. Kubota YU4210, YW0981 Parts Catalog – 274-Page OEM Parts Breakdown is for the lawn and garden line. Kubota RCK60-27B Parts Catalog – 27-Page OEM Breakdown handles mower deck parts.

Access the Factory Manual and put it on your workbench – you’ll use it every time a B6100DT rolls in.
